NEEDLE-MACHINE.

SPECIFICATION forming part of Letters.v Patent No. 404,337, uated May28, 1889.

Application filed February 8, 1889. Serial No. 299,207. (No model.)

To all whom it may concern:

Be it known that I, JOHN BERRY, a citizen of the United States, residingat Springfield, in the county of Hampden and State of Massachusetts,have invented new and useful Improvements in Needle-Machines, of whichthe following; is a specication.

This invention relates to that class of needle-machines in whichneedle-blanks are automatically fed and presented one by one to theaction of a clamping or ehucking device, which device then moves forwardto carry the needle-blank to the action of devices or mechanism forperforming the desired operation thereon, and for then withdrawing saidblank from such mechanism and discharging same from the machine.

The object of the invention is to provide automatically-operatingmechanism in needlemachines comprised in the class referred tosuch, forinstance, as blank-swaging machines or needle-groovin gmachines-whereby, at the time of the action directly upon theneedleblank by the swaging-dies or grooving mechanism of the machine,the reciprocating movement of the needle-carrier will be comparativelyslow, as necessarily required at such time; but at the time of themovement of the needle-carrier to withdraw the needle-blank from themechanism for operating thereon, for receiving and clamping or chuckinga new blank and carrying same forward to the essential operatingmechanism, the movements of the needle-carrier will be accelerated, suchlatter movements, of course, occupying much less time than if theirspeed were uniform, the capacity of the machine being therefore greatlyincreased.

In the accompanying drawings this invention is illustrated and is shownas applied on and with relation to a needle-swaging machine, by the useof which pieces of wire cut into proper lengths for blanks from which tomake sewing machine needles are successively and automatically fed to aposition to be chucked by a carrier chuck or clamp, after which chuckingthey are carried to and forced' through' an opening in a separableswaging die-block, and the swaged and attenuated needle-blanks are thenretired from the dies and discharged from the chuck and from themachine, and such machine and the operation thereof are fully describedand shown in Letters Patent of the United States granted to me, datedNovember 22, 1881, numbered 249,822.

Figure 1 is a plan view and partial longitudinal section of theneedle-swaging machine, substantially as illustrated in said LettersPatent, with the automatic mechanism of this invention applied thereon.Fig. 2 is a view in side elevation of the said improved mechanism and asmuch of the machine in connection with which it operates as will clearlyshow its operative connection and arrangement. Fig. 3 is an elevation atright angles to the one Fig. 2, as seen to the right of the line n: x.Fig. 4 is a sectional View in detail, as indicated by the line y y, Fig.3, of a counter-shaft and fixed and loose pulleys thereon; and Fig. 5 isa plan and partial sectional View of a modified form of mechanism, to behereinafter referred to.

The needle-blanks y are guided by the mechanism indicated at E', to bepresented one by one to the clamping action of the chuck e, the movementof which chuck from its position shown in Fig. 1 is next forward toclamp the blank, then rearward, resuming its position shown in said Fig.1, permitting the needle sustaining and guiding devices E to be movedlaterally out of the line of travel of the chuck, when the needle isconveyed to and forced into the opening of the swagingdies c. The needleis then, by the chuck, Withdrawn to or about the said position shown inthe drawings, being then ejected from the chuck, completing oneoperation of the machine. The needle supporting and guiding devices Eare then rearwardly moved to the position shown, as the irst step ofanother operation.

11 represents the main shaft-of the machine,

on which is a driving-pulley, 13, and there.

are cams 10, 182, and g4, and weighted cords 14 19, which, throughsuitable connections with the main operatin g parts of the machine,impart thereto the movements mentioned, and all as fully described insaid Letters Patent hereinbefore referred to, to which reference may behad.

A represents an overhead shafting, having IOO thereon for eachneedle-machine pulleys a and of large and small diameters; and lrepresents an overhead counter-shaft, having thereon for eachneedle-machine a iixed pulley, d, by which, through belt 7L, said pulleyd and counter-shaft i3 are driven from the smaller pulley, a, at,comparatively speaking, a moderate rate of speed. A pulley, f, rotatingon said counter-shaft loosely and independently thereof, is driven bythe belt y from the larger pulley, l), on the driving-shaft A. Saidloose pulley fhas an extended periphery, f2, ad jacent to which and ofuniform size therewith is a pulley, (Z2, secured on the counter-shaft. Abelt, i, passes around the driving-pulley 13 of the needle-machine andone or the other of the pulleys d2 or f2, and when the said belt fi isaround the pulley d2 the machine is moving at its slower speed, but whenthe belt is around the pulley the speed of the machine is accelerated.

Mechanism for automatically eifcctin g the shifting of the belt /12 fromthe slow to the speedier pulleys d? f2, or vice versa, under myinvention, is provided in needle-machines of the character hereinbeforementioned, and consists, broadly, in providing a belt-shifter lever inproximity to the said fast and slow pulleys f2 d2, and providing` on adriving or driven shaft of the machine a cam for acting directly upon orthrough suitable interposed connections upon said belt-shifter lever forswinging it to effect the shifting of the belt.

As particularlyshown in the drawings, Figs. l, f3, and 3, thebelt-shifter D is comprised in an angular lever intermediately pivotedin overhead han ger-lugs j, one leg thereof being bifureated, as at k,to embrace the belt, and to the other belt-shifter leg, Z, is securedone end of a vertical connecting-rod, an, to the other of which isconnected one end of ahorizontal lever, n, intermediately pivoted on alug, of the needleanachine frame, and said lever a bears by its free endupon the edge of a peripheral cam, q, on the driving and cam shaft ll ofthe needlc-blank-swaging machine, said lever being held to itscam-bearing by a spring suitably applied or its equivalent.

It will be noted with reference to the relative positions of the partsin Fig. l that they are in their positions for presenting necdleblanksand chucking same, at which period of the operation of the machine thelever nis in bearing on the least-extended portion' of the cam q and thebelt-shifter caused to assume a position to place the belt upon thepulley f2 having the greatest speed, and until the parts have been movedand the needle carried to the swaging-dies such relation of the drivingconnection is maintained; but i mmediately the needle by its end isbrought to the dies, and before being further longitudinl lly movedthereinto, the cam q has turned to tilt by its extended edge the leveroperating the belt-shifter, carrying the belt onto the slowly-drivenpulley, whereupon the motion of the machine will be retarded, and willso continue on the slower speed during the swagin and atten uatinoperation upon the blank, which being completed the accelerated speed isagain resumed, and obviously the machine will be run at a maximumspeed-as it is ca pable of doing without disadvantageous re sults-atalltimes except durin g the period of the actual swaging, and thus thecapacity of the machine is increased to a considerable and importantextent.

s, Fig. 2, represents a latch-arm pivoted by one end on the lever n, andadapted, when the lever is tilted to effect the retarded driving of themachine, to be swung to engage by iis bowed or hooked portion t thestationary horizontal brace-rod fu, confining the lever against tiltingmotion, and then the machine will be run at its slower specd,as in someclasses of work may be deemed most desirable.

In the drawings, Fig. 5 is a plan view of a modiiied form of devices forcarrying out the spirit of my invention for needle-machines, in which,as shown, the maiirshaft cam Q2 is an inclined-face cam on the side of arotating disk, the lever n2 moving 'in a horizontal plane and extendedinto proximity with the Variablyspeeded pulleys d2 fl, having thebelt-shifter legs k2 formed thereon, and thus intervening connectionsbetween the lever n2 'and the belt-shifter are unnecessary, such anarrangement being in many instances advantageous; but, to the end thatan overhead disposition of the shafting may be made, it obviously is nodeparture from the invention to form the belt-shifter and thecam-actuated lever separately, interposing a connecting rod, asparticularly shown in Figs. l, 2, and

In an application for Letters Patent of the United States iiled by meOctober 29, 1889, Serial No. 289,430, devices in accordance with my saidinvention as hereinbeforc recited are illustrated and claimed, as in anarrangement upon and with relation to specific parts of aneedle-grooving machine, and on reference to the said description itwill be appar ent that the present invention embraces within its scopethe application of automatically-ol'ierating devices, in substance asde` scribed, upon machines for performing vari` ous operations onneedle-blanks, whether swagin g, groovin g, or other work, wherein theneedles are clamped and carried to the devices for directly operatingthereon and then con veyed therefrom.
